Driver powers up large LED displays
Constant-current sink LED driver is designed for billboard, marquee, instrument and other larger, general-purpose LED displays.
Catalyst Semiconductor has expanded its LED drivers with the first in a new family of devices to address large LED video displays The new CAT4016 is a 16-channel, constant-current sink LED driver designed for billboard, marquee, instrument and other larger, general-purpose LED displays in both indoor and outdoor applications

Digitally programmable potentiometers to take over
Catalyst Semiconductor has added two new digitally programmable potentiometer (DPP) ICs to its AE2 (analogue EEPROM) mixed-signal product line.
The CAT4016 LED channels can operate with an output voltage as low as 0.4V (for 2 to 100mA LED current), to enable more power-efficient designs.
The maximum LED current is set by an external resistor.
A high-speed, four-wire serial interface with up to 25MHz clock frequency, controls each individual channel using a shift register and latch configuration.
A serial output data pin allows multiple devices to be cascaded and programmed via one serial interface.
The CAT4016 also features a thermal shutdown protection function to disable the LED outputs if the die temperature exceeds a set limit.
A replacement for popular devices from Macroblock, Toshiba and others, the CAT4016 is available in a wide range of package options including 24-lead SOIC, TSSOP, QSOP and TQFN (4 x 4mm).
The CAT4016 LED driver is priced at US $0.54 each in 10,000-piece quantities.
Samples of the CAT4016 are available now.
Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
